i am doing tthis project where i need to write a cd

*klunk*
Why?
is there any way that through
java interface cd writing is posssible. Not really no.
i know that
this is platform dependent and hardware dependent as well but let's not worry about such trivialities
but then also is there a
code in java which works for even one computer
only.
JNI you mean.
thnxxxxxxxxxx in advace.plllllllllllllllllllllllllzzzzzzzzzzzzz stop with the multiple letttttttttttttters thanxxxxxx
Honestly... give this up. This is not a suitable Java project. Choose something else for your thesis or whatever it is you are doing.

Need help writing a Java rule in PDF Forms
I have created an invoice for my contractors via "forms", and in turn made each cell either a drop down list or "read only" field so they cannot change the rate of pay, etc. Here is my issue...My first drop down cell is titled "Job Description". When the contractor selects one of the 8 dropdown options within the Job Description field, I would like it to automatically fill in the hourly rate that is associated with that particular job description (or skill). I currently have my "rate" cell as a drop down, and I want to make that a read only, and when you select the A1 position from Job Description, it will populate the "rate" field with the appropriate amount for that A1 rate. I believe this can be done with writing some Java script, but I have never played with Java and I don't really have the time to teach myself. If anyone can help with me a quick tutorial, or even the formula I should use, so that I can just plug and play, that would be super helpful. If this is a time consuming issue, I would be interested in paying someone to do it for me. Thank you!
Hi George,
I was able to copy my data over to a fresh document, and now it works just fine....thank you so much for your insight and help!
I have another question if you have a moment.
I am trying to do a simple calculation of start time and end time for my employees. Do I need to do this via a javascript, and if so, what area in properties of the result field should I copy it to? for the purpose of the script, the fields are as follows:
DataField1 = start time
DataField2 = end time
DataField3 = total time
I would like to use the h:MM tt format for my time fields if possible.
I've attached a link to the file through my dropbox account, and you'll notice that I created three new fields at the top of the invoice just to test the time calculations before i mock up the whole document.

Any help you can give me would awesome!

through Java and if yes then send me the code for theIt's possible, as there are several commercial offerings out there.
But as YOU need to write it it won't do for you to try and trick someone else into writing it so you can submit it as your own.
same . Also on which GSM Modem will it Work , I've
heard about Nokia GSM Modem N32. Kindly Guide me
regarding the Same.All depends on how you implement it.
A real server would have its own hardware and software to pipe directly into the network of a telco, and a contract with that telco to use their network to send messages. -

Now , am not a very good Java DEv. and i need to find a soln. to this prob within 1 week.
The next step is to write the data to the DB.
Am sending an example of my file:
<Start>
<Machine>
<Hostname> IPCServer </Hostname>
<HostID> 80c04499 </HostID>
<MachineType> sun4u [ID 466748 kern.info] Sun Ultra 5/10 UPA/PCI (UltraSPARC-IIi 360MHz) </MachineType>

<EthernetAddress> 09:00:30:C1:34:90 </EthernetAddress>
<IPAddress> 149.51.23.140 </IPAddress>
</Machine>
</Start>
Note that i can have more than 1 machines (meaning that i have to loop thru the file to be able to write to the DB)
Cal u tellme what to do!
Even better- do u have a piece of code that will help me understand and implement the database writing portion?
I badly need help here.

Writing a Java-enabled Media Player
Hello out there,
it's me, I was the one to put so much effort in writing a full-fletched Java Media Player that was hopefully gonna be able to compete with Winamp or Windows Media Player one day. Some of you might remember, it was Polytox Jazz, certainly a beautiful piece of software that was meant to take User Interface to a new level even Apple hasn't come up with yet. It would still be state of the art even today. But the Sun staff let me down back then. I kept on writing and writing and filing bugs, but the JMF staff weren't able to sort things out, not even the most simple things. Did I write: Listen, with plain uncompressed wave files, all is well, but as soon as I use MP3 files, I am not even able to get a peak level in sync. So, how the heck should I ever implement an equalizer? (DSP programming is known here, have read all the important books.) No answer from Sun. I was really disappointed then and dropped all the stuff forever. I'm not gonna try it again, but this is my question: Is there any cool Java Media Player around? Has anybody had any more success than me? When I started to work with JMF, around 2001, it wasn't more than a preliminary hack of freaks that didn't really know what they were doing.
Best
PhilipHi Philip, Please I want to run/actuate my cell/mobile phone front view camera (that is real life only run/actuates on video calls) through Java media/player control function and developing and importing an API. Please help me to find an appropriate trick to do so.
Please I wrote a Java Program that is successfully working for its back view camera (main camera). I tried my best to modify this program to run/actuate my front view camera, despite lots of efforts, still not successful. Please if U email me at '[email protected]' I can send U this code and successfully working jar file or can bring the source code at the forum for modification. Please help me. -
Hello,
I am trying to do an FTP through java. Does anybody know how I can spawn an FTP process and send ftp commands to it from my java program?
I am on a Solaris system BTW.
Thankyou in advance...I see you haven't assigned any duke dollars to your question. Let me tell you how does the Duke Dollar system work. Observe the following example...
I know the answer.
My rates are as follows:
zero duke dollars - vague hint
one to five duke dollars - +definite answer
six to ten duke dollars - +full file/package name
ten to fiteen duke dollars - +URL information
more than fifteen duke dollars - +full URL with download information
Pick your choice and select the appropriate answer:
0 - There are premade classes that allow you to use FTP in Java.
1 - 5 IBM have created a package that will allow you to do things that you desire.
6-10 You should be looking for the FTP Beans Suite by IBM It comprises of two beans - the FTPProtocol bean and the FTPUI bean, both are very useful, especially in your situation.
11-15 You can find this suite at http://www.alphaworks.ibm.com
16+ go here http://www.alphaworks.ibm.com/ab.nsf/bean/FTP to add file transfer functions to your applications... without writing a line of code. -
What is the best way to call SSH commands through Java technologies
What is the best way to call SSH commands through Java technologies
I don't think you can specify the password at the prompt using ssh. Plink has the -pw command option for passwords. What I did was except ssh to ask me and write the password programmatically through the outputStream I obtained from my Process object. I looked for "password: ", and then wrote the password with a trailing newline.
Both plink and ssh will also ask if you trust the host if it is the first time you are connecting to it. So before just writing the password, check if the program wants verification from you: normally supplying "y" or "n". This should only have to happen the first time the client connects. It looks like thisPLINK:
The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's key fingerprint is:
1024 f8:43:61:4c:a2:5b:77:be:5b:a7:bb:1f:f7:79:b3:b7
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)
SSH:
The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
RSA key fingerprint is e1:02:13:c8:52:c2:23:41:9b:5b:58:2c:18:e6:59:af.
Are you sure you want to continue connecting (yes/no)?What I did was read character by character from the inputStream until I found things of interest ... like "password: ". You only need to search for this in your method which will launch the ssh or plink Process. Once you have verifyed yourself, you can just pass commands to the Process, which is an ssh connection.
My suggestion is to read() each byte from the Process's inputStream and write it to stdout. Look and see what you need to be looking for so you can interactive with the program correctly. You can't use readLine here becuase when the ssh asks for the password it does not print a newline. I do know for sure, that ssh will simply print, "passowrd: ". Plink will print this as well if the -pw option is not supplied. -

Need Help-How Store the input parameter through java bean
Hello Sir,
I have a simple Issue but It is not resolve by me i.e input parameter
are not store in Ms-Access.
I store the input parameter through Standard Action <jsp:useBean>.
jsp:useBean call a property IssueData. this property exist in
SimpleBean which create a connection from DB and insert the data.
At run time servlet and server also show that loggging are saved in DB.

Error while running executable file through java in WinNT
I would like to run an executable file with Java.
- If I try with notepad or paint, i.e. Windows Applications,
I have no problem.
- I also can run Non-Windows-Own Applications, except one.
I get an error message, if I want to run this program through Java.
I have tried following commands to run an executable file.
Runtime.getRuntime().exec("cmd.exe /c "+command);
Runtime.getRuntime().exec("cmd.exe /c start "+command);
Runtime.getRuntime().exec("cmd.exe /c start /wait "+command);
Runtime.getRuntime().exec("cmd.exe /k start "+command);
command : the path to the executable file
I can run the application directly, if I click the icon on desktop,
but not through Java.
here is the error message I get
screenshot : http://www.aykut.de/error_message.jpg
Text : "Security Check failure"
The Logon System has been tampered with.
The Administrator will need to re-install.
my Idea :
The application is "old".
I think it was written for Win 3.1.
Therefore I don't know if there is any other
possibilty to run a "DOS Exe File" through Java.I have just figured out how it works,
if somebody else here in forum have this problem,
here is the solution :
String path = "F:\...\...\Application.exe";
String envDir = path.substring(0, path.lastIndexOf("\\"));
String[] command = {"cmd.exe", "/c", "start", "/wait", "/D"+envDir, path};
Process process = Runtime.getRuntime().exec(command);
"start /Dpath" => path: environment directory F:\...\...\
"start /wait" => wait until Application.exe terminates
if you use Win95 or Win98 use command.com instead of cmd.exe

Error while trying to access BPEL process through java on localhost
I have a service (CreditRatingService that comes along with install) running on the BPEL engine. Trying to invoke it through java. However, I get an exception. Below is more information. Appreciate any help.
My method
public String invokeBpel()
Map payload;
Hashtable jndi = null;
try
String ssn ="1234";
String xml = "<ssn xmlns=\"http://services.otn.com\">" + ssn + "</ssn>";
Locator locator;
locator = new Locator("default","welcome1",jndi);
IDeliveryService deliveryService =
(IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
NormalizedMessage nm = new NormalizedMessage( );
nm.addPart("payload", xml );
NormalizedMessage res =null;
try
res = deliveryService.request("CreditRatingService","process", nm);
catch(RemoteException oNameEx)
System.out.println(oNameEx.getMessage());
payload = res.getPayload();
System.out.println( "BPELProcess CreditRatingService executed!<br>" );
System.out.println( "Credit Rating is " + payload.get("payload") );
catch (Exception e)
System.out.println("This is the exception" + e);
System.out.println(e.getStackTrace());
finally
return "toPage3";
}//end method
Exception text

this implies to be in the same initial context then the bpel engine, whicuh you cannot be as long as you are not either part of the ejb code of orabpel or a child of it. and if you are you can use the Locator API without the jndi properties.

Issue with sending mail through java stored procedure in Oracle
Hello
I am using Oracle 9i DB. I created a java stored procedure to send mail using the code given below. The java class works fine standalone. When its run from Java, mail is sent as desired. But when the java stored procedure is called from pl/sql "Must issue a STARTTLS command first" error is thrown. Please let me know if am missing something. Tried the same code in 11.2.0.2 DB and got the same error
Error:

Edited by: user12050615 on Jan 16, 2012 12:18 AMHello,
Thanks for the reply. Actually I have seen that post before creating this thread. I thought that I could make use of java mail to work around this problem. I created a java class that succesfully sends mail to SSL host. I tried to call this java class from pl-sql through java stored procedure. That did not work
So, is this not supported in Oracle ? Please note that I have tested this in both 9i and 11g , in both the versions I got the error. You can refer to the code in the above post.
Thanks
Srikanth
